Re: My ptfe is in half

The new extruder design captures the PTFE tube, so even if the tube is split in several pieces it should stay in place.
In a pinch I had to combine the 'ok' parts of a couple bad PTFE tubings until replacements arrived. So you should be ok.

Re: Reduce warping curl in ABS prints?

First crank your bed temp up, I run mine around 110C. Second, are you using a cooling fan at all or maybe a breeze is going across the bed? I find that if the print is cooled unevenly or unexpectedly, the hour glass shape happens. I have gotten past most warping problems with ABS by raising the HBP,...

Re: Air in extrution?

The only filament I have not had problems with is Ultimachine's. The cost is a bit more then you can get via e-bay or other cheaper sites. But it's not that much more, $18-$20 per pound of ABS.

Re: Help choosing a second 3d printer

I voted other. I have a Printrbot LC+ and like it, ~8x8x8 print area, no failures and build sturdy. The only things I don't like about it is the dual Z-axis motors, I prefer a single motor with a belt connecting them (makes for easier setting/zeroing the z-axis) and I think it takes 3.0mm filament o...

Re: Air in extrution?

Have you tried to 'flush' out the air? You may have to run the extruder for a little bit (push 6-8 inches into it).
Otherwise the filament is to blame. I have found that air comes from cheap or poor quality filament and it causes it to expand on exit of the tip.

Do you have the old extruder design or the new one? I had the same problem with the old extruder design, I had to take apart the resistor housing and completely clean it out. I reassembled with a tiny bit of RTV to form a gasket between the two parts of the housing and tightened the assembly screws ...

Re: Aqua Net

That's interesting! I will have to try that. Does this work for PLA also? How heavy of a coat do you put on? Does it leave a residue on the printed object? Can it be cleaned off?

Re: PLA Jams

You are probably running the extruder too hot. I usually raise the temp until the extruder just feeds the filament out the nozzle.
Then I add a few degrees to that number and I have my temp for PLA.

Once the ceramic housing cracks the resistor is mostly garbage. Like BrainSlug83 said, replace it, not worth trying to fix or reuse.

Re: I melted my PTFE liner

300 degree C at the thermistor holes means that the inner parts are at a higher temperature. Not surprising that the PTFE started to melt. Good thing the liners come out and are replaceable :-).

Re: First few Prints

Looking good! I tried to print the companion cube as my first print 8 months ago, it didn't go as well as yours :-).
You may need a fan pointed at the print object to help with the top/small print areas and maybe slowing down the print.
